METHOD OF PAINTING URINALS.

No Drawing. Application filed October 23, 1926, Serial No. 143,790, and in Switzerland October 29, 1925.

It has been customary heretofore to paint the walls and floors of urinals with black japan and to apply thereon, after it has dried, a coating of disinfecting oil. It has been found, however, that the oil did not adhere firmly and was washed away after a short time, so that the coating had to be renewed every five or six days.

My invention has for its main object to obviate this defect.

Contrary to all expectation it has been found that much more durable coatings can be obtained when, according to this invention, the surfaces are first coated in the known manner with black japan, and then, after it is dry, the surfaces are provided with a second coating of black japan, the disinfecting oil being applied to the latter while it is still wet, or before it has dried.

It has been found that in this manner the oil adheres to the surface so firmly that the coating is effective for at least two to three months and, in addition, has the advantage that liquid is prevented from adhering to it. Consequently, conveniences painted in this way can be kept sweet and free from smell without trouble or expense. The convenience can be used at once after being painted as described. To renew the disin fecting coating it is sufiicient to paint the surface once more with black japan and again apply the oil to the still wet coating.

I claim 1. The method of painting urinal surfaces, comprising the steps of coating the surfaces with black japan, allowing the same to dry, applying a second coating thereof, and finally applying to said second coating before it has dried a coating of disinfecting oil.

2. A method of disinfecting urinals, comprising the step of applying a coating of disinfecting oil to a coating of a black japan before the latter is dry.

In testimony whereof I aflix my signature.
